WHEEL FOB MOTOR-CARS AND OTHER VEHICLES.

Application filed April 14, 1911.

1 t; (1H iv/L07 it may concern Be it known that I, 1\RTI[UR FREDERICK Ilwwnsnnr, a British subject, residing at l airhaven, county of Lancaster, England, have invented certain new and useful lmprovements in \Vheels for hlotor-Uars and other Vehicles, of which the following is a specification.

This invention relates to pneumatic wheels in which three or more pneumatic cushions are inserted in or applied to the body of the wheel near or adjacent to the periphery, each of such cushions comprising a pnclr .matic tube with a cover on both sides clamped to the wheel body. The covers for these cushions have generally been made by winding a suitable cord backward and forward, radially or otherwise, between rings or stiffened edges arranged at the inner opening and outer periphery of the cover, and have subsequently been placed in a vulca-nizing press with a suitable quantity of rubber, and vulcanized to form a solid sheet. I have found, however, that there is a tendency for these cushion covers, after being in use for some time, to split between the different cords, and this invention is designed to overcome this defect.

This invention consists essentially in combining with the radial cords of the cushion, a second cord laid spirally, annular-1y, or otherwise across the radial cords and in a plane at approximately right angles thereto, to prevent the cushion splitting, the whole being subsequently vulcanized with rubber in the ordinary way to form the complete cushion cover.

The :invention will be fully described with reference to the accompanying drawings.

Figure 1. is a side elevation showing the type of wheel with pneumatic cushions to which the invention is applied. Fig. 2. is a side elevation of a partially constructed cushion cover showing the position of the radial cords and the cross cords, the latter being spirally arranged. Fig. 3. is a section of the same before being shaped and vul canized. Fig. at. is a side elevation of a partially constructed cushion showing the position of the radial cords and the cross cords, the latter having an annular arrangcment. Fig. 5. is a similar elevation showing the cross cords as having an undulating arrangement. Figs. 6 and 7. are sect-ions similar to Fig. 8 but showing modifications. Fig. 8. is a side elevation of a partially con- Specification of Letters Patent.

structed cushion cover showing the position of the radial cords, the cross cords being in short lengths.

The two rings A A may be of metal or other suitable material, the ring A of a diameter equal to the outer edge of the cushion, and the ring A of a diameter equal to the central opening or inner edge of the cushion. ()rer lhese rings a cord 13 is wound lmrluvard and loiwvard, preferably radially, (or at an angle to the radius of the outer ring A). The cord I3 is preferaliily wider on one surface than the other, that is,--l'lat or oval in cross secti(m,--und is laid fiat on the outer ring A, and on its edge on the inner ring A in order to fully close up the intervening spaces as in lligs. E3 to land The cord B may however be an ordinary round cord as in Fig. 8. The cords I) are coated or saturated or impregnated with rubber and a layer or coating of rubber is laid over them when in position. Over the surface formed by the cords B a second cord (1 is laid, preferably in a spiral, each coil being a suitable distance from the next as in lig. 2, or in a series of annular rings as in Fig. l, or in an undulating spiral or rings as in Fig. 5, or in short sectional lengths as in Fig. 8. The cord C may be flat, round, oval or other suitable shape. The cord C is preferably laid on the outside surface ofthe cover, as indicated in Fig. 3, though it may be laid on the inside surface as indicated in Fig. (3, or inserted between the cords B as indicated in Fig. 7. Over the cords so arrangedv a layer or sheet of rubber is laid. The cover so formed is placed in a vulcanizing mold and molded and vulcanized to the desired shape in the ordinary way. The cord (3 thus applied across the cords it binds the latter together and, while allowing a certain freedom of movement of the cords l3, prevents the cover splitting by preventing the cords 13 opening out or spreading laterally too far when in wear.

hat I claim as my invention and desire to protect by Letters Patent is 1.. A cover for vehicle wheel cushions comprising a pair of (o-axial rings, a cord looped radiallybaclnvard and forward across and around said rings, and a cord laid across the radial loops of the first-named cord to prevent the cover from split-ting.

2. A cover for vehicle wheel cushions comprising a pair of co-axial rings, a cord looped. radially baclnvard and forward across and around said rings, and a cord laid approximately at right angles across the radial loops of the first-named cord to revent the cover from splitting.

3. A cover for vehicle wheel cushions comprising a pair of co-axial rings, a cord wider in one direction than in the other looped radially backward and forward across and around said rings, said cord being laid fiat on the outer ring and edgewise on the inner ring, and a cord laid across the radial loops of the first named cord to prevent the cover from splitting.

l. A cover for vehicle wheel cushions comprising a pair of co-axial rings a cord wider in one direction than in the other looped radially backward and forward across and around said rings, said cord being laid fiat on one ring and edgewise on the other ring, and a cord laid spirally across the radial loops of the first-named cord to prevent the cover from splitting 5. A cover for vehicle wheel cushions com prising a pair of co-axial rings arranged in spaced parallel planes, one of said rings having a diameter less than that of the other ring, a cord wider in one direction than in the other looped radially backward and forward across and around said rings, said cord being laid flat on the second-named ring and edgewise on the first-named ring, and a cord laid across the radial loops of the first named cord to prevent the cover from splitting.

6. A cover for vehicle wheel cushions comprising a pair of coaxial rings arranged in spaced parallel planes, one of said rings havmg a diameter less than that of the other v ring, a cord looped radially backward and forward across and around said rings, and a cord laid across the radial loops of the first-named cord to prevent the cover from splitting.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
